Dozens of the DC-SRF-injector parameters have been considered in the optimization. Some measurements of the electron beam are also introduced, including emittance measurement with the three-profile method, energy spread measurement with analyzing magnet and beam length diagnostics with zero-phasing method. These studies indicate that the injector beam quality satisfies the requirement of the FEL-THz facility.
